Physics comparison with vanilla

This page contains the reports of the automated physics tests for all supported versions that have been tested. It is automatically updated every time a new build is created in the github actions.

It works by comparing the trajectories of a vanilla client and a botcraft client in a given configuration with the same player inputs (keyboard and mouse). A checkmark means that for all the ticks the difference between the position of the botcraft bot and the vanilla client was below the threshold. A cross means the position was too far away from the vanilla one. For more informations on the automated physics tests, you can check the physics wiki page.
